Hi, I found a 290x on newegg for 259 dollars on sale, but r9 390 costs 320+. What is the difference? Also, just a side question, should I get a 290x/390 and wait for pascal or the next amd series, or just buy a 980 ti/fury x and upgrade in 2-3 years? I plan on gaming in 1440p once I get a monitor. Thanks for any replies.
